It's got scratch damage. Not big and long scratches, but just the worn away type due to plastic shell + using without case. If I had to give a rough estimate of surface area scratched, perhaps 10-20ish %. Not as bad as it seems though, at 2 feet away you can't really tell.
The top and bottom have dents due to drops on concrete. Although the phone still retains its original shape due to smoothing out of the dented material over time. Dents not sharp.
Screen has no issues at all. Camera glass outer protective layer scratched on top, affects photo quality ever so slightly. Pictures are overlaid with a tiny square shaped thing of what appears to be due to a chip in the protective layer.
International version, unlocked, with a performance-based rom installed.
Not sure if this is relevant as I've never seen other i9000's in the wild, but the back case says "with Google", so perhaps it's a Google edition?
In terms of accesories it has none. It's got a 16GB sd card which I'm debating whether or not to include, and no charger. At most I could bundle it with the USB cable.
